Aeolus II was a wind turbine in the Jade wind farm near Wilhelmshaven from 1993 to 2008 . It was the successor to Aeolus I , Gotland, Sweden and was the largest wind turbine in the world at the time it was commissioned. The complex is named after Aeolus , the Greek god of the winds.
Manufacturer
The plant was built by the Swedish Kvaerner AB and put into operation by the German Messerschmitt-Bölkow-Blohm (MBB).
Technical details
The Aeolus II had a 92 m high prestressed concrete tower , a 3 MW generator driven by an angular gear unit and two hydraulically adjustable GRP rotor blades 40 meters long, which means that the turbines had a rotor diameter of 80 m. The tower foundation rested on 36 concrete piles that are deeply anchored in the clay soil.
From today's perspective, the following technical features were:
- the bevel gear, which enabled power to be transmitted to a generator located in the tower and thus solved the cable twisting problem common in wind power plants at the time.
- the rail system attached to the tower, which made the tower accessible from the outside with a platform so that the rotor blades were accessible over their entire length. When setting up the system, the complete machine house with mounted rotor blades was moved on this rail to the top of the tower, rotated by 90 ° at the top and mounted. So there was no need for a tower-height crane.
business
The system went into operation on October 15, 1993 and was initially owned by PreußenElektra . In 2000 the system was taken over by Dietmar Knünz and Heiner Wendt, who were also involved in the development at MBB at the time, and continued to operate it until the end of 2007. A damage to the main rotor bearing made repairs uneconomical, so that on February 13, 2008 the system was blown up. The entire system was turned over with the rotor installed. An Enercon E-70 with 2.3 MW output was installed at the Aeolus II site.
